V.S. Subrahmanian

Visiting Professor
Ph.D., Syracuse University
Special Awards/Honors: 
AAAI Fellow, AAAS Fellow

As of August 1, 2017, V.S. Subrahmanian is at Dartmouth College.


Subrahmanian is a visiting professor in the Department of Computer Science and in UMIACS.

He is the director of the Center for Digital International Government (CDIG) and co-director of the Laboratory for Computational Cultural Dynamics (LCCD). From 2004 to 2010, he served as the director of UMIACS.

Subrahmanian's research is at the intersection of databases, artificial intelligence, and optimization methods with applications to tracking, monitoring and forecasting behaviors of terrorist groups, socio-cultural groups, global health care, and other areas relevant to most human beings.

His work in artificial intelligence spans rule-based expert systems and logic programs, nonmonotonic reasoning, probabilistic reasoning, temporal reasoning, hybrid reasoning, and software agents. Subrahmanian's database work focuses on heterogeneous database integration and interoperability, logic databases, probabilistic databases, and multimedia databases.

In the last few years, he has been studying how to reason about massive collections of multilingual document collections and mine them for sentiment/opinion information, as well as how to mine ontologies directly from text. Subrahmanian has been applying his work to the study of foreign cultures and terrorist groups with the intention of automatically extracting data about a group’s organization and activities, and mining this information in order to build stochastic behavioral models of the group which, in turn, can be used to come up with forecasts of future behavior of the group. His group has built several scalable systems for these and other purposes, which have been applied extensively in government and industrial applications.

Subrahmanian received the National Science Foundation (NSF) National Young Investigator Award in 1993 and the Distinguished Young Scientist Award from the Maryland Science Center/Maryland Academy of Science in 1997.

He received his doctorate from Syracuse University in 1989.
